Rose plant 75-20031 jacdew

ABSTRACT

A floribunda rose variety having a bush which blooms continuously through the growing season; glossy foliage; orange-red blooms which fade to lighter color before falling; little or no fragrance; numerous prickles.

This present invention relates to a new and distinct variety of roseplant of the floribunda class which was originated by me by crossing thevariety America, U.S. Plant Pat. No. 3,682, with an unnamed variety.

The primary objective of this breeding was to produce a new rose varietyof the floribunda class with abundant blooms and disease resistantfoliage. This objective was substantially achieved along with otherdesirable improvements as evidenced by the following unique combinationof characteristics which are outstanding in the new variety and whichdistinguish it from its parents, as well as from all other varieties ofwhich I am aware:

1. A floribunda type bush, blooming continuously through the growingseason.

2. Foliage glossy and nearly immune to rose powdery mildew.

3. Blooms of orange-red fading to a lighter color before falling.

4. Very little or no fragrance.

5. Numerous large and small prickles.

Asexual reproduction of this new variety by budding, as performed atWasco, Calif., shows that the foregoing characteristics and distinctionscome true to form and are established and transmitted through succeedingpropagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor in terminology in accordance with The Royal Horticultural SocietyColour Chart except where ordinary dictionary significance of color isindicated.
